WILBER E. ARNOLD, OF MADISONVILLE, OHIO, ASSIGNOR TO THE VICTOR SAFE &LOCK COMPANY, OF CINCINNATI, OHIO, A CORPORATION OF OHIO.

VAULT AND STRONG-ROOM DOOR.

To all whom it may concern:

Be it known that I, \VILBER E. ARNOLD, a citizen of the United States,and residing at Madisonville, Hamilton county, State of Ohio, haveinvented certain new and useful improvements in Vault and Strong-RoomDoors; and I do declare the following to be a clear, full, and exactdescription thereof, attention being called to the accompanying drawing,with the reference characters marked thereon, which forms also a part ofthis specification.

This invention relates to certain improve-.

ments in the construction of doors for vaults and strong-rooms, theparticular feature concerning the manner of supporting such a door, sothat it may be conveniently manipulated.

In the following specification and particularly pointed out in the claimat the end thereof will be found a full description of my invention,together with its manipulation, parts and construction, which is alsoillustrated in the accompanying drawing, in which Figure 1, is ahorizontal section through such a door and the frame to which it isfitted, the door being shown in closed position. Fig. 2, is a similarview and shows the door open. Fig. 3, is a front-view of the door in itsclosed position and as it appears in Fig. 1. Fig. I, is a verticalsection through the door and its frame, taken on a line l-4: of Fig. 1,and looking in the direction of the arrow shown there. Fig. 5, shows atop-view of the door-frame. Fig. 6, is a section taken on a line 6-6 ofFig. 2, the lower part only of the door being shown.

A shows part of the front wall of a vault or strong-room, a door-openinga being provided to permit access.

B is a door-frame preferably rectangular and set into this opening inthe wall, its op posite upright sides b-b of the frame forming the jambsof the door.

C is the door fitted to this frame and movably supported so that it mayprevent passage through the opening surrounded by the frame when closedand permit it in either direction when open.

The construction of the door and of its frame is so devised that eitheror each of them may be made in form of a casting,

which may be of non-machineable metal like manganese steel for instance.

Flanges 8-8 extending outwardly from the frame are provided whichreceive between them the masonry of wall A and thereby serve to hold thedoor-frame se curely seated in the wall-opening.

The door is in form of a rectangular slab of solid metal, convex betweenits longer, upright edges, so as to form in substance a segment of acylinder. It is provided on one of its upright edges with a lip 9 and onits other edge with a shoulder 10.

In the closed position of the door as shown in Fig. 1, its li 9 strikesagainst a shoulder 11, and shou der 10 on the door which projectsoutside of the periphery thereof abuts against a shoulder 12, bothshoulders projecting inwardly from the door-j ambs. A tight closure isthus obtained which prevents the introduction of explosives at theupright edges of the door. The

door has a swinging movement for opening or closing, it movlnghorizontally in its own plane as best shown in Fig. 2. It is supportedfor such purpose on pivots, one 13, seated in the sill l4: and the other15 being seated in the lintel 16 of the doorframe. Engagement of thedoor with these pivots is by hubs 17 carried at the ends of arms 18,which project from the inside of the door at lower and upper edges of itand preferably radially arranged. The horizontal edges of this door meetthe edges of forwardly extended arts 19 and 21 of sill and lintelrespective said extended parts completing the closure when the door isin the closed position shown in Fig. 1. These opposite edges meet in amanner which prevents the introduction of liquid explosives, for whichpurpose tongues and complementary grooves are provided thereat. Thegrooves are arranged to be inverted so as to be incapable of retainingliquid explosives and to prevent also the accumulation of dust and dirt.For such purpose a groove 22 is provided in the lower edge of the door,to receive a tongue 23 which projects up wardly from the front edge ofthe extended sill. Above, a groove 24: is provided in the underside ofthe forwardly extended part of the lintel to which is fitted a tongue 20at the upper edge of the door. It will now be noted, by observing Fig.&, that upwardly open joints are avoided by this arrangement which wouldfavor the introduction of explosives in liquid form.

Means, which by reducing friction and by carrying part of the weight ofthe door facilitate its manipulation, may be provided at its lower edge.They may be in form of ball or roller bearings provided within groove22, or such rollersmay be provided in a manner as shown at 25, theytraveling upon the sill and its forwardly extended part. The sill bypreference is also extended-rearwardly as shown at 26, to provide asurface for these rollers to travel upon.

Smaller doors of limited weight may be manipulated directly by hand,suitable handles or knobs being provided for the purpose.

For heavier doors suitable mechanical devices are provided as forinstance a rack 27 on the outer side of the door, into which a pinion 28is fitted which is supported on a, bracket 29, connected to adjacentparts of the door-frame. A handle 31; is provided, p e er b y e e able,vw ere y the pin n. may be rotated,

ui able locking means, usua ly ne r more bolts 82, to, be actuated by atime-lock 83., may be provided. These bolts are seated in the door nearone of; its edges and adapted;

to move into sockets, 34 provided in adja cent parts of the door-frame,said sockets being so: located as to be opposite the ends. of the boltswhen the door'is in closed position.

Where a number of bolts are used, they are all attached to a bar 85;,whereby they are simultaneously; moved, said bar being operativelyconnected to the time-lock, to be actuated thereby.

When the door and its frame are made of non-machineable metal as beforealluded to, I provide for inserts of machineable metal which are placedduring the casting of these parts, to permit machine and hand tool-workwhere such is necessary, as for instance to provide for the guide-waysand sockets of the locking-bolts, the attachment of the time-lock, forthe formation of rack 27 and for the connection of bracket29 and forbearings for rollers 25.

For all other Work, finishing of the door and the frame and fitting ofthe edges of the former into this latter, grinding is resorted to. V

The edges of the door-frame on the inside of the vault are extendedoutwardly all around to form an attaching flange 36 which permitsconnection with the vault-lining 37.

A section of removable flooringy38 may be provided which during businesshours may be placed into the door-way, to coverthe lower arms 18 asshow-n in Fig. 6, so 3 as to provide for a level and even passagewaythrough the door+opening., It may rest on these arms and also on feet39.

I am familiar with the construction of a i plicatijonbeing prior to,mine, the scope of.

my claim should be construed accordingly j and so as not to include anyof the matter claimed in said prior application.

Having described my invention, I claim as new:

In door construction for vaults, the combination of a door in shape of acylindrical segment having converging arms projecting,

from its innerconcave side near its horiz-ontal edges and hubs supportedby these arms in a position so as to be concentric to this concavesurface, a rectangular door-- frame having sockets located opposite eachother in the horizontal members, and pivots seated in these sockets andengaging the hubs mentioned in amanner to permit the door to swing inits cylindrical plane.

In testimony whereof, I hereunto affix my signature in the presence oftwo witnesses.

WILBEB. n. ARNOLD.
